CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 344,420, dated June 29, 1886.

Application filed April 5, 1886. Serial No. 197,796. (No model.)

To all whom it may concern:

Be it known that I, IsAIArr TILLsoN, of South Abington, in the county of Plymouth, of the Commonwealth of Massachusetts, have invented a new and useful Improvement in Railway-Car Couplings; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure l is a top view of two of my irnproved car-couplings in engagement with each other. Fig. 2 is a side elevation, Fig. 3 au under side view, Fig. 4 a horizontal section, and Fig. 5 alongitudinal and median section, of one of such couplings.

The nature of myinvention is defined in the claim hereinafter presented.

This coupling is of the class in which there is ahook to engage with that of another suchv coupling in order to connect or couple two cars together. In the drawings, the said hook is shown at A as arranged below and pivoted to a draw-bar, B, adapted to slide lengthwise in atrough, C. The pivot c of the hook projects up through a chamber, b, in the drawbar, provided with a movable cap,c. Through the said pivot and in the said chamber is a bar, d, that extends between the free ends of two springs, e e, arranged as represented and secured within the chamber. From the drawbar a rod, g, projects rearwardly through two iianged tubes or thimbles, h t', which are arranged as represented, and to slidelengthwise in two partitions, k Z, extending across the trough,therebeingbetween theheads orflanges m and encircling the rod g a spiral spring, n. The rod at its rear end is screw-threaded, and has a nut, o, screwed upon it and against the end of the rearmost thimble. The hook A is slotted horizontally and lengthwise of it, as shown at p, and has within the slot a bent lever, q,which at 0r near its middle is fulcrumed to the hook. A chain, r, connects the tail of the lever with the lower arm of another lever, s, the latter lever being 'fulcru med to a bar, u, extending across and fastened to the trough. Furthermore, there is within the draw-bar head a mouth. o, to receive a link, w, for connecting the draw-bar to another, as occasion may require, a pin, x, for engaging the link going down through the said mouth.

Vhen two cars provided with couplings. as set forth, are brought together for being coupled, the two hooks of the couplings will each press the other aside until their heads may pass one another, which taking place, each will be forced toward the other and will hook upon or couple with it. To disengage them we have only to so move one of the levers in each hook as to cause such lever to crowd the two hooks out of engagement with each other. On the draw-bar being pulled forward within the trough, the front thimble will serve as an abutment to support the spiral spring,v

which will be contracted lengthwise by the rear tliimble being drawn against it. So on the draw-bar being moved rearward in the trough the rear thimble will in like manner serve as an abutment to the spring, and such spring will be contracted lengthwise by the front thimble being forced against it.

I claim* The combination of the draw-bar B, provided with the link-receiving mouth and pin, with the supporting-trough C, having transverse partitions lc Z, the rod g, nuto, thimbles h t', and spring n, the hook A, its tripping-lever q, and the bar d, and springs e e, for actuating such hook, all being arranged and to operate substantially as set forth.
